Inelastic Corrections Testing

Prerequisites

Container Subtraction tab

Time required 1 - 3 minutes

  1. Go to Interfaces > Inelastic > Corrections

  2. Go to the Container Subtraction tab

  3. With the Sample combo box set to File click browse and select the file irs26176_graphite002_red from the Sample Data folder

  4. With the Container combo box set to File click browse and select the file irs26174_graphite002_red from the Sample Data folder

  5. Click Run

  6. This should plot a blue subtracted line on the embedded plot. A workspace ending in _red should be produced

  7. Change the Spectrum value and the plot should be updated with the corresponding workspace index

  8. Check that when clicking Plot Current Preview, it will open a pop-up window with the current preview plot

  9. In the Output Options, select Open Slice Viewer using the down arrow, it should open the Slice Viewer with the generated dataset

  10. In the Output Options, select Plot 3D Surface using the down arrow, it should open a surface plot for the generated dataset

  11. In the Output Options, select indices 50-51. A red asterisk should appear, preventing you from using Plot Spectra

  12. In the Output Options, select indices 49-50. It should be possible to click Plot Spectra to plot a two spectra graph

Calculate Paalman Pings Tab

Time required 1 minute

  1. Go to Interfaces > Inelastic > Corrections

  2. Go to the Calculate Paalman Pings tab

  3. Read the deprecation message. This tab should be removed for the release of version 6.12 assuming no user feedback.

Calculate Monte Carlo Absorption Tab

Time required 3 - 5 minutes

  1. Go to Interfaces > Inelastic > Corrections

  2. Go to the Calculate Monte Carlo Absorption tab

  3. With the Sample combo box set to File click browse and select the file irs26176_graphite002_red from the Sample Data folder

  4. Choose the Sample Shape to be Flat Plate

  5. Sample Height & Width should be 1.0

  6. Sample and Container Thickness should be 0.1

  7. Sample mass density should be 1.0. The Sample formula should be H2-O

  8. Container mass density should be 6.0. The Container formula should be V

  9. Click Run and wait.

  10. A group workspace ending in _Corrections should be created. Keep this workspace for the Apply Absorption Corrections test.

  11. In the Output Options, the combo box should have four entries ending in _ass, _assc, _acsc and _acc.

  12. In the Output Options, try using the Plot Wavelength and Plot Angle options.

Apply Absorption Corrections Tab

Time required 1 - 3 minutes

  1. Go to Interfaces > Inelastic > Corrections.

  2. Go to the Apply Absorption Corrections tab.

  3. With the Sample combo box set to File click browse and select the file irs26176_graphite002_red from the Sample Data folder.

  4. With the Corrections combo box set to Workspace, and select the workspace ending in _Corrections from the previous test.

  5. Tick Use Container and select the file irs26174_graphite002_red from the Sample Data folder.

  6. Click Run and wait.

  7. This should plot a blue corrected line on the embedded plot. A workspace ending in _red should be produced

  8. In the Output Options, select Open Slice Viewer using the down arrow, it should open the Slice Viewer with the generated dataset

  9. In the Output Options, select Plot 3D Surface using the down arrow, it should open a surface plot for the generated dataset

  10. In the Output Options, select indices 50-51. A red asterisk should appear, preventing you from using Plot Spectra
